TestCase.java file:


    @Entity
    @Table(name = "test_case", schema = "testcase")
    @JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)
    @XmlRootElement
    public class TestCase implements Serializable {
    
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        @Column(name = "ID", nullable = false)
        private Long Id;
    
        public Long getId() {
            return Id;
        }
        public void setId(Long id) {
            Id = id;
        }
    }

**DBUtil.java** runs the DDL and DML hsql files and DB is created successfully(I have printed DB on console).

      public class DBUtil {
                public static void createTestSchema() {
                    String sqlPath = "src/test/resources/sql";
                        ApplicationContext dbCtx = new ClassPathXmlApplicationContext("applicationContext-junit-test.xml");
                BasicDataSource ds = dbCtx.getBean(BasicDataSource.class);
                Connection conn = ds.getConnection();
                        Statement st = null;
                    try {
                        System.out.println("Creating Schema !");
                        File dir = new File(sqlPath);
                        File[] files = dir.listFiles();
                        SqlFile sqlFile;
                        for (File file : files) {
                                sqlFile = new SqlFile(file);
                                sqlFile.setConnection(conn);
                                sqlFile.execute();
                            }
                        }
    }

DaoImpl.java
我的 HQL 查询获取零结果（如果我将 hbm2ddl.auto 设置为“create”） 我的 HQL 查询抛出 JDBCExceptionReporter：用户缺少权限或找不到对象（如果我不使用 hbm2ddl.auto 属性）

public class DaoImpl implements Dao {
    @Autowired
    private SessionFactory sessionFactory;

    public void getAllData(){

        String hql = "FROM TestCase";
        Session session = sessionFactory.openSession();
        List<TestCase> results;
        try {
            Query query = session.createQuery(hql);
            results = query.list();  // list is empty : []
            
        } catch (Exception e) {
            
        }
    }
}

Answer 1

来自 TestCase.java

我删除了 @Table 中的架构并且它起作用了。我还删除了 DDL 中的 Create Schema 和类似的参考。

所以更新后的 TestCase.java 将如下所示：

@Entity
@Table(name = "test_case")
@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)
@XmlRootElement
public class TestCase implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "ID", nullable = false)
    private Long Id;

    public Long getId() {
        return Id;
    }
    public void setId(Long id) {
        Id = id;
    }
}

Answer 2

您的数据库 URL 属性对于内存数据库是错误的。正确使用file:和mem:database的属性如下：

    <property name="url">
        <value>jdbc:hsqldb:file:testcasedb;shutdown=true;hsqldb.write_delay=false;</value>

    <property name="url">
        <value>jdbc:hsqldb:mem:testcasedb</value>

如果您将 shutdown=true 与 mem: 数据库一起使用，则所有数据都会在最后一个打开的连接关闭后立即删除。使用文件数据库，保存所有数据。
